In VM I have found one anomaly recently. Say you want to define two lists, with one list subscribed to the other and you have chosen short names (8 chars or less) and long names (LIST-ID= keyword) short long subscribers ===== =========== =========== m abcdefghijk z, abcdefg abcdefg xxxxxxxxxxx y, w When you email to: M, the mail "bounces" from xxxxxxxxxx because it thinks that it is a duplicate. The "trick" is not not define any "short" name lists that can overlap OTHER leading "long name" list. Pete Weiss at Penn State
